It's one of the most commonly Googled questions about the lifestyle and it deserves a straight answer rather than a vague reassurance. So here it is: some do, some don't, and most couples have a clear conversation about it before they start playing with other people.
There's no single answer
The lifestyle doesn't have one uniform approach to protection. Some couples use condoms consistently for all penetrative sex with new partners. Some have a different approach for oral sex versus penetrative sex. Some couples who've been in the lifestyle for years have established trusted connections with other couples and have different arrangements within those. Some people bareback by preference.
What most experienced people in the scene have in common is that they've thought about it deliberately and talked about it with their partner before they ended up in a situation where a decision needed to be made on the spot. The couples who haven't had that conversation in advance are the ones who end up in awkward or regrettable situations.
What the research actually says
There's genuinely mixed data on STI rates among people in the lifestyle. Some studies from the Netherlands and Belgium have shown higher STI rates among swingers than the general population, which makes intuitive sense given more sexual partners. Other research has found that people in consensual non-monogamous relationships aren't dramatically more at risk than people who are monogamous, partly because swingers tend to test more regularly and be more deliberate about safer sex than people having affairs or one-night stands.
The honest position is that more partners means more potential exposure. That's not controversial. But a swinger who tests every three months, uses condoms for penetrative sex and knows their status is in a very different risk category from someone in a nominally monogamous relationship who cheats occasionally, never tests, and assumes they're fine.
Condom use in practice
Condom use for penetrative sex is common in the lifestyle, particularly with new or infrequent partners. Most people consider this the baseline sensible approach. A Dutch study tracking lifestyle participants between 2011 and 2018 found that condom use for vaginal sex was around 60%, down from 73% in 2011. Anal sex saw higher consistent condom use.
Oral sex is where practice varies most. Most people in the lifestyle don't use barriers for oral sex, which is consistent with broader sexual health norms but does carry some risk for certain infections including gonorrhoea, herpes and syphilis. This is worth knowing rather than assuming oral is risk-free.
Testing
Regular STI testing is genuinely standard practice among active lifestyle participants. Most people test every three to six months, some more frequently. NHS sexual health clinics offer free testing and most are used to seeing patients who are open about having multiple partners. The conversation is not as awkward as many people expect.
If you're new to the lifestyle, getting tested before you start and then regularly after is just sensible practice. Knowing your status means you can be honest with people you play with, which is the foundation of how this scene is supposed to work.
PrEP
PrEP (pre-exposure prophylaxis) is a medication that significantly reduces the risk of HIV transmission and is available free on the NHS. It's relevant primarily for people who have unprotected sex with partners whose HIV status isn't known. If this applies to how you participate in the lifestyle, it's worth looking into. Your GP or sexual health clinic can advise.
Talking about it with new partners
In a well-functioning lifestyle encounter, this conversation happens before you get to a play situation. Most experienced couples are used to it and won't find it awkward. If someone reacts badly to you asking about testing or stating your preferences about protection, that's useful information about whether this is someone you want to play with.
Stating your preferences clearly is not a mood-killer. It's what adults who take this seriously do. The community expects it.
The short version
There's no universal rule in the lifestyle about protection, which means you need to know your own approach before you're in a situation where you need to state it. Think about it, talk to your partner, and get tested regularly. That's what responsible participation looks like.
